TRANSMISSION DEVICE, RECEPTION DEVICE, RATE CONTROL DEVICE, TRANSMISSION METHOD, AND RECEPTION METHOD

摘要

A CPU (14) detects the value of the output bit rate for media data output from a buffer (17), detects the free space of the buffer (17), and calculates the reduction rate by dividing a subtraction value, which is determined by subtracting a reduction rate set value from the detected free space value, by the allocation time. When the input bit rate of the media data that is input to the buffer (17) is lowered in response to the output bit rate value, the CPU (14) adds the detected output rate value and the calculated reduction rate value and lowers the input bit rate value based on the upper limit value of the input bit rate, which is the addition value.
